Polycom 3725-76302-001O manual Field Description

Conference Manager Configuration

Field	Description
Cascade for size	Enables conferences using this template to span Polycom MCUs to achieve
	conference sizes larger than a single MCU can accommodate.
	This option and Cascade for bandwidth are mutually exclusive. See About
	Cascading on page 193 for more information about enabling cascading of
	conferences.
Video switching (VSW)	Enables a special conferencing mode that provides HD video while using
	MCU resources more efficiently. All participants see the current speaker full
	screen (the current speaker sees the previous speaker).
	If this mode is enabled:
	• The minimum line rate available is 768 kbps (except for SD resolution,
	available only on v7 and newer Polycom MCUs with MPM+ or MPMx
	cards).
	• All endpoints must connect at the same line rate, and those that don’t
	support the specified line rate are connected in voice-only mode.
	• The video clarity, layout, and skins settings are not available.
	• LPR is automatically turned off, but can be turned back on.
	If this option is off, conferences using this template are in Continuous
	Presence (CP) mode, in which the MCU selects the best video protocol,
	resolution, and frame rate for each endpoint according to its capabilities.
H.264 high profile (v7.6)	Sets a VSW conference to use Polycom’s bandwidth-conserving H.264 High
	Profile codec (previously supported only in continuous presence mode).
	If this is selected, all endpoints in the conference must support High Profile.
	Endpoints not connecting at the conference's exact line rate and resolution
	are connected in audio-only mode. Available only on v7.6 and newer Polycom
	MCUs with MPMx cards.
Resolution	Available only if Video switching is selected. Offers the following resolution
	settings:
	• H.264 1080p30 (available only on Polycom MCUs with MPM+ or MPMx
	cards)
	• H.264 720p30
	• H.264 720p60 (available only on Polycom MCUs with MPM+ or MPMx
	cards)
	• H.264 SD 30 (available only on Polycom MCUs with MPM+ or MPMx
	cards)
	• H.264 1080p60 (available only on the RealPresence Collaboration Server
	1800 MCU or Polycom MCUs with MPMRx cards)
